Arm 9 has a camUnited States Patent M COMBINED TAPE FEEDING, SEVERING, AND DELIVERINGMECHANISM Kurt Aurbach, Bielefeld, Germany, assignor to Anker- Werke, A.G., Bielefeld, Germany, a corporation of Germany Application July 20,1950, Serial No. 174,831 Claims priority, application Germany October 6,1949 Claims. (Cl. 164-49) The invention relates to cash registers,calculators, accounting machines and the like business machinery and,more particularly, to devices for'printing and issuing a check, voucheror other record in such machinery.

In the known machines of this kind, the control means that actuate thecutter for severing the printed record slip from the supply tape areseparate in design and location from the means for dispensing the slip.

It is an object of the invention to improve the record producing andissuing mechanism of business machines toward a simplified design ofgreatly reduced space reguirements as compared with the correspondingknown evices.

To this end, and in accordance with a feature of the invention, thedrive structure for operating the perforating or cutting device isdesigned as a guide for issuing the check or record thus eliminating theneed for separate dispensing devices.

These and other objects and features of the invention will be apparentfrom the example of a check-dispensing printing device according to theinvention described in the following and illustrated on the drawing, inwhich Figure l is a side elevation, Fig. 2 is a sectional top view, Fig.3 is a sectional detail view on a larger scale of elemerits in the lefttop portion of the device as illustrated in Fig. 1, and Fig. 4 is aperspective and exploded view of the same elements.

The illustrated check printing and issuing device has a stationary framestructure composed of two parallel wall plates 1 and 2, which arerigidly fastened together and spaced from each other by three screwbolts 3, 3a, 3b. The bolt 3 forms the pivot of a drive member 4 foractuating the reciprocable blade 5 of a tape cutter. The drive member 4is designed as a curved surface structure and has bracing corrugationsor ribs 6 which serve also as rails for guiding the severed checks fromthe cutter blade 5 to the dispensing opening of the device. Mounted onthe back of the curved drive structure 4 are a projection 7 with an arm9, and a projection 8 on which a roller 10 portion engageable by dogpins 11 and 12 of a cam disc 14 which has a cam projection 13 inengagement with the roller 10 and is mounted on a cam shaft 15. Duringthe machine operation, shaft 15 with cam disc 14 performs a clockwiserevolution (Fig. 1). During that revolution, the cam projection 13 movesthe roller 10 away from the cam shaft, thus turning the drive member 4clockwise about bolt 3 so that the cutter blade 5 is shifted toward theright into its active position. Immediately thereafter, the pin 11engages the cam end of arm 9 and returns drive member 4 and cutter blade5 to the illustrated rest position. In the illustrated position of camdisc 14, member 4 and blade 5 are secured in the rest position by thepin 11.

Drive member 4 is linked with the cutter blade 5 by projections 16 ofarm 4 which pass through corresponding openings of the blade. The bladeis guided between a top plate 17 and a traverse 18 (Figs. 1, 3, 4). Aspring 19 (Figs. 3, 4) between plate 17 and traverse 18 serves to forcethe cutter blade 5 toward the top plate 17 but can become effective onlyto an extent permitted by discs or washers 20 disposed between plate 17and traverse 18. The stationary counter blade of the tape cutter, forcoaction with the cutter blade 5, consists of a plate 21 which ismounted in a traverse 22 by means of angle pieces 21a and together witha blade 21b (Figs. 2, 3, 4).

The check tape 25 to be printed is supplied from a 2,698,660 PatentedJan. ,4, 1955 9 reel 25a revolvably mounted on a stationary reel shaft26 and passes over a guide roller 26a to a driven feed roller 24. Roller24 coacts with a pinch roller 23 to feed the tape over a guide 26bthrough a slot 260 and across the path of the cutter blade 5 into achute bordered at one side by the above-described curved guide surfaceof the drive member 4 and at the other side by a sheet-metal cover plate27 partly surrounding the tape reel 26. A sheet-metal guide 28 adjoiningthe pivoted lower end of the drive member 4 forms a slide surface forthe checks to be issued so that they reach the bottom of guide 28 fromwhich they can readily be removed through the outwardly flared checkdispensing opening formed'between plates 27 and 28.

The check printing place is located between the guide roller 26a and thefeed roller 24 (Fig. 1). The printing is done by printing platens o1hammers 29, 30 which, when moved upwardly, force the adjacent tapeportion together with an intermediate ink ribbon (not shown) against thetype carrying means of the machine schematically shown at 31 (Fig. 1).The lower end 32 of hammer 29 abuts against a nose 32a of a controllever 34 pivoted on a shaft 35. Lever 34 carries a roller 36 which actsas a cam follower in cooperation with a cam 33 on cam shaft 15. Thelower end 37 of hammer 30 abuts against a nose which is shaped andarranged like nose 32a but appertains to another control lever pivotedon shaft 35 and coacting with another cam 33a (Fig. 2) of cam shaft 15.During the revolution of cam shaft 15, the cams 33 and 33a cause thecontrol levers to lift the printing hammers at the proper moment toproduce an imprint on the check tape portion then located at theprinting place.

The driven feed roller 24 (Fig. l) is actuated from the cam shaft 15 tooperate in the necessary time relation to the printing and cuttingdevices. To this end, a gear 38 on cam shaft 15 has one or severalperipherally limited series of teeth that enter into an intermittentmeshing engagement with a pinion 39. Driven from pinion 39 is a train ofgears 40, 41, 42 of which the gear 42' meshes with a pinion on the shaftof the feed roller 24.

The operation of the device as a whole is as follows. When, during themachine operation, the cam shaft performs its revolution, the printercontrol cams 33, 33a first actuate the printing hammers 29, 30 so that acheck is printed on the tape portion between rollers 26a and 24. Then,the teeth'of gear 38 temporarily actuate the feed roller 24 through theconnecting gear train 39 to 42 and advance the tape an amountcorresponding to the length of the printed check to be issued. In thismanner, the printed portion passes through the slot 260 beyond thecutter blade 5. Next, the cam projection 13 of the cutter control cam 14engages the roller 10 and turns the cutter drivemember 4 clockwise aboutpivot bolt 3 so that cutter blade 5 moves beyond the edge of counterblade 21 and cuts'the printed check from the tape. The severed checkdrops into the chute between the rocking drive member 4 and the coverplate 27 and slides over the inclined surface of plate 28 to the checkdispensing opening.

If so-called double checks are to be issued, the printing and cuttingoperations are repeated in such a manner that the first operation of thecutter blade merely perforates the tape while the second operation,occurring after the second printing, cuts the printed double check offthe tape. in order to permit such an operation, the cutter blade ispreferably given a serrated cutting edge as shown in Fig. 2, and it isnecessary to provide cam 14 with a second cam projection 13 shaped toadvance the cutter blade only to the extent required for perforating thetape.

It will be apparent to those skilled in the art upon a study of thisdisclosure that the invention is not limited tothe design specificallyembodied in the described and illustrated example but can be modified invarious respects and inaccordance with the requirements and desiderataof the particular application, type, and construction of variousbusiness machines, without departing from the objects and essentialfeatures of the invention and within the scope of the claims annexedhereto.
